SAFETY ATTACHMENT FOR LOCOMOTIVE-CABSK.

Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed August 25, 1914. Serial No. 858,447.V

To all whom it may concern Be it lnown that I, WILLIAM A. U'r'rz, a

citizen of the United States, residing at' Fort Vorth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Safety Attachments for Locomotive-Cabs, of which the following is a specification.

My invention relates to safety devices for escaping from locomotive engine cabs, and more particularly to a detachable carrier to be discharged from the engineers cab in case of danger; and the object is to provide a carrier or protecting device into which the engineer can inclose himself instantly in time of danger and which device will be automatically detached from the cab and delivered to the ground or other place for the protection ofthe engineer.

The object is to provide a device which will inclose the engineer and protect him against falling on the ground or stones or other dangerous objects and which can be sealed air and water tight and provided with a valve which the engineer can operate.

The object is to protect the engineer against fire and water or hot steam and to provide a ready means of escape from the engine.

One object is to provide a carrier or deliverer which cannot be crushed or will not be crushed in times of accident and danger.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the drawings.

Reference is had to the accompanying drawings which form a part of this application.

Similar characters ofreference are used to indicate the same parts throughout the several views.

The improved safety device has a sheet metal shell 1 which may be braced on the interior by channel iron 2. The bottom'- of the shell or casing 1 is made heavy by solid` metal 3 so that the device will stand on the bottom and even resume an erect'position if it should be turned down on the side. The casing is upholstered on the interior by a lining el and springs 5 and braced by the channel iron2.. Inorder to prevent rapid passage of heat and cold through the casing, a lining of asbestos 6 may be placed next to the shell l. The carrier, shown in Figs. 1-12 is to be mounted in the engineers cab with the body iush with the floor and suspended'below'the floor of the cab. 'A

seat 7 is provided for the engineer and provision made for the descent of the seat into the carrier. Vertical bars 8 of T-iron are attached .to the channel iron 2 and project closeto the top of the body of the carrier and bars of Tsiron 9 are pivotally connected to the bars 8 in the manner shown in Figs. 6 and 7. The seat 7 is attached to the slides 10 by brackets 11 and braces 12. The slides 10 consist of channel iron with the edges bent to engage the T part of the T-irons 8 loosely so that the seat can slide upwardly and downwardly on the T-irons 8 and 9 freely.

The slides 10 will break the joints inthe T-irons 8 and 9 and the seat will be held in the normal position above the floor of the cab by pins 13 whichy are inserted in the flanges of the T-irons 8, the slides 10 resting by the vT-irons 8 and 9 and the slides 10 resting on the pins 13. The seat 7 may be made to descend into the body or casing by pulling on a lever 14 which is fulcrumed on one of the slides 10. A link bar 15 is pivotally connected to the lever 14 and pivotally connected to a bell crank lever 16 which is fulcrumed onrthe slide 10 with the lever 14. The lever 16 is pivotally connected to the jointed pin 13. Both slides 10 may be provided with levers 16 and pins 13 if necessary. A pull on the lever 14 will let the seat 7 drop to the position of the dotted outline in Fig. 2.

The carrier is provided with a lid 17 which is attached to the T-irons 9. See Fig. 2. Bars 18 connect the l`-irons 9 with the shell of the lid and the lid 17 can be attached to the T-irons 9 in any other suitable manner. rlhe lid cannot be closed until the seat descends into the carrier l, but as soon as the slides 10 pass down off the T-irons 9, the lid is free to fall. In order to make a positive throw forthe lid, a lug 19 is attached to the lid and a spring 2O is attached to a bracket 21 which is to be attached to a convenient part of the cab. The spring 20 stands compressed against the lug 19 and as soon as the seat releases the lid, it will fall, being started by the spring 20. The safety device is mounted in the cab by hinged bands or hoops 22 which are attached to the engine frame i-n any suitable manner. The bands are brought together and held in operative position by pins 23, the bands having interlocking joints to receive the pins 23. Wire cables or cords 24 and 25 are connected to the pins 23 and connected to the lid 17 so that when the lid falls, the pins 23 will be drawn from the joints of the bands 22 and thus release the bands 22 from the carrier. Additional mounting devices for the carrier consist of hanger rods 26 which are attached to the timbers of the cab and hang down by the casing or shell 1. The lower ends of the hangers 26 have holes to receive supporting pins 27 which are held normally projected through the shell 1 into the hangers 26 by springs 28. IThe pins 27 are provided with guides 29 and are automatically withdrawn from the hangers 26 when the lid falls. The pins 27 are attached to a flexible cord 30 and a cavity 31 is formed in the i weighted portion 3 of the carrier. A buffer 32 is attached to the bottom of the seat 7. When the seat falls the buer 32 will strike the cord 30 and force the same downwardly (see Fig. 2) to the position of the dotted outline. rlhis action will draw the pins 27 out of the hangers 26 and thus release the carrier from the hangers. rllhe hoops or bands 22 are connected by interlocking joints in front as well as on the back. The interlocking joint is released at the same time the interlocking joint in the rear is released by the cables 24 and 25. rlhe interlocking joint in front is held locked by a pin 33. A bar 34 is ously so that the carrier will fall out of the engine cab. The seat 7 is mounted on the slides 10 and is provided with cushion springs 37 which are supported on vertical bars 33 which rest on the platform 39. A

shield 40 is made rigid with the platform to protect the elements behind the shield. 1n addition to the braces for the seat heretofore noted, the seat is braced by the bars 18 which are connected to the lid and to the lV-irons 9. Means are provided for locking the lid in a closed position. A catch 42 is rigid with the interior of the casing and a spring catch or lock 43 is attached to the lid. When the lid falls the lock 43 will catch in the catch 42. The lock 43 is in the form of a bell crank lever and a spring 44 normally holds the lock in the locking position, but the person inside can open the lid by pressing on the back end of the lever. A person on the outside can open the lid by taking out the screw 45 which mounts the spring and thus displace the spring so that the device can be unlocked.

When the carrier starts out of the engineers cab, swinging rods 46 are used to shift the lower part of the carrier out toward the side so that the carrier will not fall directly in the railway track. The rods 46 are pivotally connected to some part of the cab and are provided with yokes 47 which engage lugs 43 on `the side of the carrier.

The safety device herein described has been set forth for the use of the engineer. 1t is apparent that the device is also adapted for the use of the fireman and other workmen on moving trains or other devices.

The lid 7 is provided with a valve 49 hingedly connected to the lid and normally closing an opening which can be used to obtain fresh air. rfhe valve may be operated by a rope or cord 50.

instead of hinging the lid to the 'l'- irons, as heretofore set forth, the lid may be hinged to the shell 1, as shown in Figs. 8-12.

The variations shown in Figs. 13-20 comprise a safety device for the same purpose as the device previously described and similar in design. The construction varies from the construction previously described. There is merely a change in the body of the device. The shell is composed of two parts 51 and 52. rFhe part 51 is the main body and the part 52 is movable relative to the part 51 and is adapted to telescope into a Y ing 65.

is approximately 180 degrees and the part 52 is provided with a handle 54V by which the engineer can close the device by pulling the movable shell around out of the space 53. The movable section 52 is guided by the outer or stationary part 51 and by a stationary half shell section 55. In this form of safety device, the entire casing, consisting 'of parts 51 and 52 mounted with the floor flush with they-floor of the cab, as shown in Figs. 13,14, and 13. Locking pins 56 may be used for mounting the casing. rIhe opening through the cab floor is lined with a flanged ring 57 and the pins 56 made to engage the ring 57. The pins 56 have upstanding lugs 58 which project up through a disk 59 which has cam slots 6() therein for the lugs 58. The disk 59 has alaterally projecting shank 61 which is perforated to receive the end of an actuating lever 62 which is fulcrumed in a bearing 63. When the disk is turned by the lever 62, the pins 56 will be drawn out of their sockets so that the casing will fall out of the cab. In order that la person may not be thrown from one end of the casing to the other a buffer or partition 64 may be mounted in the casing and drawn down within the casing by a cordl 66 until the buffer rests on supports 69 to which it may be locked by the dogs 68. The buer may be provided with upholster- A spiral spring 67 may be used to bring the disk 59 to normal position. Wien the casing starts out of the cab, a chute 70 will guide the device as it is descending and a spring 71 will bear against the opposite side to aid in giving the device the proper direction when falling. A shield 72 is attached to the step of the cab to prevent the safety device from striking the step and being thrown under the car or cab.

In the form of safety device shown in Figs. 1 to 12 inclusive, the casing 1 is hung with the top part of the casing iiush with the cab iioor and the seat 7 is mounted on a platform 39 which is flush with the floor of the cab. When the seat is thrown down, the platform 39 descends with the seat. The lid 7 has upholstering 73 which serves as a back for the seat and which will prevent the engineer from being struck by the T-irons 9 while the seat is descending. The lower T-irons 8 may be attached to the shell 1 by brackets 74 riveted to the T-irons and to the shell.

In the form of safety device shown in Fig. 20, the moving part of the device may be made in two parts 75 and 76.

In orderto make a positive throw of the lid 7, a cord ,77 may" be attached to the lid and to the seat 7, enough slack being provided to letfthe seat far enough out of the way of the lid. v
